: Hello
: Here are some questions from some high school students:
: 1. If there is no animal life present (intelligent or otherwise), when 
: the sun rises, is there color?

: 2. Is it possible (theoretically or otherwise) to split a photon? If so, 
: what would it result in?

2. A photon splits into two spin waves of equal and opposite momentum when
   absorbed by ferromagnetic matter undergoing magnetic resonance. Spin 
   waves, also called magnons (their quantum counterparts) are bosons with
   spin -1.
